The service principle of this kind of motion pedometer software is that the center of gravity will change when people walk, and the sensors and collaborators in the equipment feel the center of gravity move and count it, or use the latitude and longitude information continuously received by the mobile phone or the number of times the mobile phone swings to calculate the movement distance and steps. Due to the shaking degree of mobile phone, positioning error, network signal and other reasons, the accuracy of step counting will have certain errors.
I hope I can help you.
